This is a Fastchip computer chip that came out of my 1990 Iroc 350 TPI. It was done by Ed Wright Automotive. I have all original paper work that came with this chip which will be included. This chip will work for any 90-92 F-body 350 TPI Auto. The program on the chip is for a mild build, nothing crazy. I paid $175 for this chip.

Here are some quick specs on my setup
Full exhaust, SLP headers with Single 3" piping. Ported heads and intake. BBK FPR. BBK 58mm throttle body.
Compcams Camshaft specs:
Basic Operating RPM Range: 1,200-5,200 RPM
Duration at .050" lift: 212 int./218 exh.
Valve lift with 1.5 ratio: 0.488 int./0.495 exh. lift

Asking $75 OBO
